ai.onnx.Shape

ai.onnx · standard ONNX operator · ONNX opset ≥ 15

Description

Returns a 1-D tensor containing the shape of the input tensor. Optional start and end attributes select a slice of the shape axes; negative values count from the back, and axes are clamped to [0, rank].

See the ONNX Shape spec for the reference semantics.

• metadata.json — kernel metadata (id, digests, provenance)
• manifest.json — the op contract (source of truth)
• test.json — correctness cases
• bench.json — benchmark + tuning cases
• shape.wgsl.jinja

Use with @huggingface/kernels

The loader derives every required output's shape and logical dtype from the manifest contract and this call. It then allocates the result tensors automatically.

The version: 1 option selects the published kernel contract; it is independent of any operator opset, contrib since_version, or model version.

Replace each *Data placeholder with a typed array containing the corresponding input data.

import { getKernel } from "@huggingface/kernels";

const kernel = await getKernel("webgpu-kernels/ai.onnx.Shape", { version: 1 });
const { shape } = await kernel({ data: { data: dataData, shape: [1, 2, 2] } });
